What you're trying to do is pretty straight forward. I do this here in my lab all the tiem. Can you show us your flowgraph? How are you running tx_waveforms? Are you using a USB 3 port? How's the B200 connected to the oscilloscope? On Mon, 27 Jul 2020 at 21:58, Aaron Smith via USRP-users < usrp-

Marcus, I have tried frequencies ranging from 75-450 MHz. My scope is good to 500 MHz. I have tried gain settings betweeb 30 and 60. I am using RG-174, which is good to 1000 MHz. In my custom code I generate tones by sending repeating samples with a value of 0.8. In the past this caused tones to

Hello all, I am trying to output a sine wave from a B200 using custom code, or the UHD tx_waveform example. In either case, when I view the output on an o-scope, there is not a pure sine wave. The output looks more triangular wave. I have used this scope with other B200s and the same code to get a
